Function Documentation

◆ CopyFromWeakArray()

template<typename DestArrayType , typename SourceArrayType >

void CopyFromWeakArray	(	DestArrayType &	Dest,
		const SourceArrayType &	Src )

Utility function to fill in a TArray<ClassName*> from a TArray<TWeakObjectPtr<ClassName>>

Definition at line 414 of file WeakObjectPtrTemplates.h.

◆ GetTypeHash()

template<typename T >

FORCEINLINE uint32 GetTypeHash ( const TWeakObjectPtr< T > & WeakObjectPtr )

Hash function.

Definition at line 428 of file WeakObjectPtrTemplates.h.

◆ MakeWeakObjectPtr()

template<typename T >

FORCEINLINE TWeakObjectPtr< T > MakeWeakObjectPtr ( T * Ptr )

Definition at line 318 of file WeakObjectPtrTemplates.h.

◆ operator!=() [1/2]

template<typename LhsT , typename RhsT , typename OtherTWeakObjectPtrBase , typename = decltype((LhsT*)nullptr != (RhsT*)nullptr)>

FORCENOINLINE bool operator!=	(	const LhsT *	Lhs,
		const TWeakObjectPtr< RhsT, OtherTWeakObjectPtrBase > &	Rhs )

Compare weak pointers for inequality

Parameters

Other weak pointer to compare to

Definition at line 304 of file WeakObjectPtrTemplates.h.

◆ operator!=() [2/2]

template<typename RhsT , typename OtherTWeakObjectPtrBase >

FORCENOINLINE bool operator!=	(	TYPE_OF_NULLPTR	,
		const TWeakObjectPtr< RhsT, OtherTWeakObjectPtrBase > &	Rhs )

Definition at line 310 of file WeakObjectPtrTemplates.h.

◆ operator<<()

template<class T , class TWeakObjectPtrBase >

FArchive & operator<<	(	FArchive &	Ar,
		TWeakObjectPtr< T, TWeakObjectPtrBase > &	WeakObjectPtr )

Weak object pointer serialization, this forwards to FArchive::operator<<(struct FWeakObjectPtr&) or an override

Definition at line 438 of file WeakObjectPtrTemplates.h.

◆ operator==() [1/2]

template<typename LhsT , typename RhsT , typename OtherTWeakObjectPtrBase , typename = decltype((LhsT*)nullptr == (RhsT*)nullptr)>

FORCENOINLINE bool operator==	(	const LhsT *	Lhs,
		const TWeakObjectPtr< RhsT, OtherTWeakObjectPtrBase > &	Rhs )

Compare weak pointers for equality. If both pointers would return nullptr from Get() they count as equal even if they were not initialized to the same object.
